   Precision castings thermal correction, divided into two heating and heating partial overall. When more difficult to correct certain stainless steel cold precision castings, can be partially heated by hammering or press to correct. Large thick-walled castings correction should be heated as a whole, before correcting measured amount of deformation needed correction.
  Then, put on the horns of the heat treatment furnace, pad proper pads, in the above parts need correction, applying an appropriate load, during the heat treatment, with loads of action, the amount of deformation rectified. If the stainless steel precision castings after heat treatment to correct, it should be to eliminate stress after tempering correction, correction of temperature and stress relief tempering temperature, tempering the heat treatment temperature should be lower than 10-20 ℃.
   Correction is cold hammer, manual presses, jacks, friction or hydraulic presses, stainless steel precision castings for normal correction. Suitable for simple geometry, a small amount of deformation, the small thin-walled castings, or plastic deformation of the large but well-cast aluminum alloy castings, and large deformation of quenched aluminum castings. When casting complex structure, it can be corrected by means of correction of the mold.
